Factors can be found using different methods. Mentioned below are some commonly used methods:

1. Finding factors using multiplication
2. Finding factors using division method
3. Prime factors and Prime factorization

To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 1555. Identifying the numbers which are multiplied to get the number 1555 is the multiplication method.

Step 1: Multiply 1555 by 1, 1555 × 1 = 1555.

Step 2: Check for other numbers that give 1555 after multiplying

5 × 311 = 1555

Therefore, the positive factor pairs of 1555 are: (1, 1555) and (5, 311). All these factor pairs result in 1555. For every positive factor, there is a negative factor.

Dividing the given numbers with the whole numbers until the remainder becomes zero and listing out the numbers which result as whole numbers as factors. Factors can be calculated by following a simple division method -

Step 1: Divide 1555 by 1, 1555 ÷ 1 = 1555.

Step 2: Continue dividing 1555 by the numbers until the remainder becomes 0.

1555 ÷ 1 = 1555

1555 ÷ 5 = 311

Therefore, the factors of 1555 are: 1, 5, 311, and 1555.

The factors can be found by dividing it with prime numbers. We can find the prime factors using the following methods:

• Using prime factorization
• Using factor tree

Using Prime Factorization: In this process, prime factors of 1555 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1555 ÷ 5 = 311

311 ÷ 311 = 1

The prime factors of 1555 are 5 and 311. The prime factorization of 1555 is: 5 × 311.

The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -

Step 1: Firstly, 1555 is divided by 5 to get 311.

Step 2: Now divide 311 by 311 to get 1. Here, 311 is a prime number, that cannot be divided anymore. So, the prime factorization of 1555 is: 5 × 311.

Factor Pairs: Two numbers that are multiplied to give a specific number are called factor pairs. Both positive and negative factors constitute factor pairs.

• Positive factor pairs of 1555: (1, 1555) and (5, 311).

• Negative factor pairs of 1555: (-1, -1555) and (-5, -311).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 1555 are 1, 5, 311, and 1555.

• Prime factors: The factors which are prime numbers. For example, 5 and 311 are prime factors of 1555.

• Factor pairs: Two numbers in a pair that are multiplied to give the original number are called factor pairs. For example, the factor pairs of 1555 are (1, 1555) and (5, 311).

• Multiple: A number that is the product of a given number and an integer. For example, 1555 is a multiple of 5.

• Prime factorization: The expression of a number as the product of its prime factors. For example, 1555 can be expressed as 5 × 311.
